To the north of the Ninth Division, two divisions of the Thirteenth Corps, the Thirty-first to the south and the Fifth to the north, had beaten furiously against the German line upon the Oppy-Gavrelle sector. The efforts of these divisions were greatly handicapped, as in the case of others, by the very early hour at which the action had begun, and by moonlight in the earlier hours, which exposed the assembly of the troops. Starting in pitch darkness the brigades lost touch and direction, so that they were unable to reach their objectives with the speed and precision which is so necessary if barrages and machine-guns are to be avoided. The 92nd East Yorkshire Brigade of the Thirty-first Division advanced upon Oppy Wood, and found itself among trees in the darkness with criss-cross lacings of barbed wire from the branches in every direction, and a heavy fire beating on their ranks. The obstacles would have been difficult in day-time, but were impossible at night. The battalions got completely mixed up, and finally a strong German attack drove them back to their trenches, in spite of a most strenuous resistance, notable for many deeds of valour, for one of which, the single-handed attack upon a {82} machine-gun, Lieutenant Harrison of the 11th East Yorks received a posthumous Victoria Cross. The 93rd West Yorkshire Brigade had got off well and had reached its objective, but this successful German attack exposed the 16th West Yorkshires, who were the flank battalion, to pressure upon its left rear, so that they had eventually to fall back. This exposed the 15th and part of the 18th West Yorkshires, who were now holding Gavrelle village and the trenches to the immediate north of it. For a time things were very critical, and the windmill which commanded the village was retaken by the enemy. The Colonel of the 15th West Yorks collected sixty men of his battalion and held splendidly to the east side of the village for the whole day. One company of the 18th Durhams under Lieutenant Hitchings was sent to retake the windmill, which they did, but were driven out again by the shattering fire of the enemy. They re-formed at the foot of the slope and attacked and recaptured the mill once more, only to be driven out for the third time. Again they took the mill, and this time they drove back the German counter-attack and held on to the position. Sixty out of a hundred in the British ranks had fallen, but when the battle painter of the future is in search for a subject, he will find none better than that of the forty survivors under their boy leader, wearied, blood-stained, but victorious in their shot-torn mill. The whole Gavrelle position was now held, the 93rd being strengthened by two battalions from the 94th York and Lancaster Brigade.
